KREO® Sleep + Recovery

A key electrolyte that helps maintain hydration and supports nerve and muscle function. It also helps your body hold onto fluids during training.

What it does: Glycine is an amino acid that helps your body shift into a calmer, sleep-ready state. In human studies, taking ~3 g before bed has been associated with better subjective sleep quality and falling asleep faster, and may support feeling more refreshed the next day.

Naturally found in: High-protein foods and collagen-rich foods like meat, fish, bone broth, gelatin, and some legumes.


Source

What it does: PEA is a fatty acid–like compound your body naturally makes to help regulate inflammation and discomfort, which is why it’s often used in recovery-oriented formulas. Most of the clinical research is in comfort/pain support (not specifically “sleep”), but improved comfort can indirectly support better rest and recovery.

Naturally found in / derived from: Present in small amounts in foods like egg yolk and soybeans; supplements use a purified form.

What it does: GABA is a calming neurotransmitter your nervous system uses to “turn down the volume” on stress signals. The science on oral GABA supplements is mixed: reviews generally find limited evidence for stress benefits and very limited evidence for sleep, so it’s best described as a relaxation-support ingredient rather than a guaranteed sleep “knockout.”

Naturally found in / derived from: Found in fermented foods (and produced in the body). Many supplements are made via fermentation.

What it does: PeptiSleep is a branded ingredient made from rice protein that’s been hydrolyzed into bioactive peptides. It’s positioned to support sleep quality and deeper sleep cycles, and it has ongoing/registered clinical research investigating sleep outcomes in adults.

Derived from:Rice (Oryza sativa) protein peptides.

Clinical Study

What it does: L-theanine is an amino acid best known for supporting a “calm but alert” state—helpful when your brain feels wired at bedtime. Systematic reviews and trials suggest it can support relaxation and may improve certain sleep measures in some people, without acting like a sedative.

Naturally found in:Green tea / tea leaves (Camellia sinensis).

What it does: Lactium is a milk-derived peptide ingredient studied for stress and sleep support. A double-blind, randomized crossover trial in adults with poor sleep quality evaluated Lactium’s impact on subjective and objective sleep measures, supporting its use as a relaxation/sleep-quality ingredient.

Derived from:Milk casein (a milk protein) that’s hydrolyzed into calming peptides.

What it does: Tryptophan is an essential amino acid your body uses to make serotonin, which is then used to produce melatonin—key for healthy sleep timing and sleep quality. Research consistently supports the pathway (tryptophan → serotonin → melatonin), and supplementation is often discussed in the context of sleep support through this mechanism.

Naturally found in: Protein foods like turkey/chicken, eggs, dairy, plus pumpkin seeds, soy, and legumes.
